A python program fails to execute in sublime text 3, but success in bash

Question

#-*- encoding:utf-8 -*-
from __future__ import (absolute_import, division, print_function,
                        unicode_literals)

text = "我们的世界充满了未知数。"  # Chinese

print( type(text) )        # unicode
print(text.encode('utf-8'))
print(text)                # an error occurs in sublime

The version of python is 2.7.6. The OS is Linux mint 17. $LANG in bash is en_US.UTF-8. In sublime text, Ctrl + B is used to run this toy program. The output is:

Traceback (most recent call last):
<type 'unicode'>
我们的世界充满了未知数。
  File "~/test.py", line 9, in <module>
    print(text)                # an error occurs
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-11: ordinal not in range(128)
[Finished in 0.0s with exit code 1]
[shell_cmd: python -u "~/test.py"]

or

Traceback (most recent call last):
  File "~/test.py", line 9, in <module>
<type 'unicode'>
我们的世界充满了未知数。
    print(text)                # an error occurs
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-11: ordinal not in range(128)
[Finished in 0.0s with exit code 1]
[shell_cmd: python -u "~/test.py"]

In bash, eigherpython test.py or python -u test.py runs correctly:

$ python test.py 
<type 'unicode'>
我们的世界充满了未知数。
我们的世界充满了未知数。
$ python -u test.py 
<type 'unicode'>
我们的世界充满了未知数。
我们的世界充满了未知数。

It really makes me wonder. ~~Is there any ways to run the program in sublime text correctly ?~~

Is there any difference between the environments of sublime and bash?
why the outputs in sublime text is out-of-order？

You already ran it correctly - you just need to use `.encode()`. — MattDMo, Dec 16 '15 at 02:20
@MattDMo My previous question is inaccurate. I have updated it. — letiantian, Dec 16 '15 at 02:33
Under SublimeText you're probably seeing some random interleaving of text printed to `stdout` and `stderr`. Does bash print the same string twice? — roeland, Dec 16 '15 at 03:21
My guess is that sublime is providing the wrong locale to python when running the code. Have you tried asking for help at their forum? — RedX, Dec 16 '15 at 04:05
@RedX Now I think it's the problem of bash. http://stackoverflow.com/questions/34305464/why-does-print-an-unicode-obj-in-ipython-occur-no-error — letiantian, Dec 16 '15 at 07:20

Sublime has a configuration problem. Python uses the default ascii codec when it can't determine the terminal encoding. It is figuring it out correctly in bash so it works.

If you set the environment variable set PYTHONIOENCODING=utf8 before launching sublime you can force Python to use that encoding when printing. I'm not familiar with sublime so I can't suggest how to fix its configuration.
